The 1.4.4 parser is stricter with regex capture groups and JSON token extraction . In 1.4.2, if a variable $ERROR$ wasn't defined, it would simply return null. In 1.4.4 Anomaly builds, undefined variables cause a throw exception, labeled as "Anomaly." 2.2 The Hit/Miss Logic Anomaly Symptom: The bot marks a successful login as "Anomaly" even though the HTTP status code is 200 OK and the success word is present in the source.
{"status":"success","user":null} Your config uses the capture user:(.*?) to extract a value. In 1.4.2, null becomes an empty string. In 1.4.4 Anomaly builds, null triggers a NullReferenceException internally, caught and logged as "Anomaly." If you are a legitimate penetration tester or a security researcher using Openbullet 1.4.4, follow this debugging workflow. Step 1: Enable Debug Logging Edit Environment.ini in your Openbullet 1.4.4 directory: Openbullet 1.4.4 Anomaly
This article dissects the anomaly from a technical, troubleshooting, and security perspective. Before we tackle the anomaly, we must understand the software's state. The original Openbullet (by Ruri) stopped official development around version 1.4.2. Version 1.4.4 is a community-driven modification—often referred to as "Anomaly Edition" or "Modded 1.4.4." Step 1: Enable Debug Logging Edit Environment
For defenders, anomaly rates in access logs can reveal credential stuffing attempts before they succeed. For attackers, high anomaly rates mean wasted bandwidth and unreliable results. In plain English:
Use unique success words like "dashboard" or "logout" . Step 3: Modify the Anomaly Tolerance Threshold In Openbullet.exe.config , locate:
[Debug] LogResponses=true LogRequests=true SaveToFile=true Run your config on (one username:password pair). Open the Logs folder. Compare the received response with your success/fail conditions. Step 2: Check Your Success and Fail Words The most common fix: ensure your success word does NOT appear on the fail page, and your fail word does NOT appear on the success page.
if (!successConditionSatisfied && !failConditionSatisfied) return ResultType.Anomaly; In plain English:
